The other day in the hardware store I overheard someone ask the clerk for some rose food. My eyebrows went up as I thought to m’self, “Are they kidding, thinking that roses need their own special food? Next, I’ll hear about plants that prefer vegetarian or kosher food, perhaps fish emulsion on Fridays?”
All this food science when it comes to plants may boost fertilizer sales, but it hardly bothers plants either way. Plants take up the bulk of their nutrients as ions (charged atoms or groups of atoms) that are dissolved in water in the soil. Rock particles, as well as humus and organic fertilizers, decompose to release nutrient ions slowly into the soil solution. Chemical fertilizers are already in ionic form, so when you sprinkle a handful on the soil, they dissolve as soon as they contact water.
